Well first solve for x
2x + 3 = -19
2x = -22
x = -11
Therefore yes, -11 is a solution for the function.
Answer:
h = 20 cm
Step-by-step explanation:
The volume (V) of a square based prism is
V = area of base × h ( h is the height )
area of square base = 9 × 9 = 81 cm²
Hence
81h = 1620 ← equation to be solved
Divide both sides by 81
h = 20 cm
There are 100 cm in a meter so 16 cm is equal to 1600/48
Answer:
X would equal 4
Step-by-step explanation:
5 x 4 is 20. And the equation was 5x + 1 = 21.
So, the answer would equal 20. Hope this helped!! :D
